“…In this research, a passive-pressurized hydrodynamic deep drawing (PHDD) was utilized. The die chamber and the blankholder are slightly modified in order to provide a radial pressure around the blank [21]. Figure 1 shows the modified die set for PHDD process which provides less oil leakage and a higher maximum pressure during the process.…”

The purpose of this study is to produce a desired hydroformed product under the optimal pressure profile. To achieve this purpose, a new adaptive optimization approach is proposed based on fuzzy logic control (FLC) integrated with simulated annealing (SA) optimization technique and ANSYS parametric design language (APDL). An intermediate MATLAB code was developed and used to manage data transfer automatically between FLC, SA and APDL, in which there would be no need for any interaction of user/designer during the optimization process execution. This method aims to find the optimal pressure loading profile, prevent wrinkling and necking failures, reduce unsuccessful iterations, and enhance convergence precision. This method is capable of adaptively changing the process parameters in order to reach the optimized values with higher accuracy in a more reasonable time. The results show a good agreement between the proposed optimization approach and experiments. The developed optimization approach is a practical and reliable design tool for industrial production of any symmetric shell cups using hydroforming process.

“…The raw bimetal composites containing substrate and cladding can change into partial individual substrate without surface cladding, such as stainless steel cladding, aluminum cladding and copper cladding; the cladding reveals obvious localized necking and multiple fracture failure during the cold rolling process. That is to say, the function properties containing high corrosion resistance and high electrical conductivity of bimetal composites, have disappeared [42][43][44][45]. Du and Fan et al [46] proposed that the clad interface of the multilayered Ti/Al composites after cold rolling revealed severe multiple necking and nonuniform layer thickness.…”

Multilayer metal composites have great application prospects in automobiles, ships, aircraft and other manufacturing industries, which reveal their superior strength, toughness, ductility, fatigue lifetime, superplasticity and formability. This paper presents the various mechanical properties, deformation characteristics and strengthening–toughening mechanisms of laminated metal matrix composites during the loading and deformation process, and that super-high mechanical properties can be obtained by adjusting the fabrication process and structure parameters. In the macroscale, the interface bonding status and layer thickness can effectively affect the fracture, impact toughness and tensile fracture elongation of laminated metal matrix composites, and the ductility and toughness cannot be fitting to the rule of mixture (ROM). However, the elastic properties, yield strength and ultimate strength basically follow the rule of mixture. In the microscale, the mechanical properties, deformation characteristics, fracture behavior and toughening mechanisms of laminated composites reveal the obvious size effect.

“…Hashemi et al [18] proposed a process window diagram to predict minimum and maximum critical pressures in HDD of conical cups using Hill yield criterion numerically. In another work, the same authors [19] proposed an adaptive finite element simulation for hydroforming of bimetal composite sheets to predict producibility of any symmetric cupshaped products. Zhang et al [20] studied the use of hydromechanical deep drawing (HMDD) for the three layers simultaneous forming of the metallic blanks to fabricate a hemispherical structure.…”

In this paper, a theoretical model was proposed to stress analysis and calculate the critical fluid pressure path corresponding to rupture instability in hydro-mechanical deep drawing (HMDD) of hemi-prolate spheroid (HPS) cups. This model is based on Barlat and Lian yield criterion and maximum drawing force condition was utilized to rupture instability analysis. The effects of material and process parameters were investigated on critical fluid pressure path. The results demonstrated that maximum permissible fluid pressure is increased by enhancement of sheet thickness, strain hardening exponent, anisotropy and reduction of friction coefficient. Decrease the difference between semi-major and semi-minor axis of the hemiprolate spheroid, enlarges safe zone. Finally, a serial of HMDD experiments were accomplished to verify the theoretical critical fluid pressure path. Theoretical results agree well with experimental data.
